Find the area of the shaded polygons:

tigry1 [53]

Answer:

Step-by-step explanation:

Purple: This makes two trapezoids. A=(a+b)/2 times h

1st = (4+1)/2 x 1 = 2.5

2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5

Total = 2.5+7.5=10

Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh

1st = 1/2x2x2 = 2

2nd = 1/2x2x2 = 2

Total = 2+2=4

A local hockey rink is covered by a dome in the shape of a hemi-sphere (half sphere). if the floor of the arena has a diameter o

8_murik_8 [283]

The surface area of hemisphere is given by:

$Surface Area = 2 \pi r^{2}$

Where r is radius of hemisphere.

We are given diameter = 250 ft.

We know that radius = half of diameter.

Radius of dome = 1/2 (250) = 125 ft.

Now let us plug the value of radius in the formula,

$Surface Area = 2 (3.14) (125)^{2}$

Surface Area of dome = 98125 square foot.
